JOHN A. GEE, OF CRIPPLE CREEK, COLORADO.

Specification of Letters Patent.

Patented March 5, 1907- Application filed September 13, 1906. Serial No.334,529.

To all whom it may concern:

Be it known that I, J OHN A. GEE, a citizen of the United States,residing at Cripple Creek, in the county of Teller and State ofColorado, have invented certain new and useful Improvements inFly-Escapements for Window and Door Screens; and I do declare thefollowing to be a full, clear, and exact description of the invention,such as will enable others skilled in the art to which it appertains tomake and use the same.

This invention relates to improvements in fly-escapements for'window anddoor screens.

The object of the invention is to provide an attachment for window anddoor screens through which flies and other insects may readily find anexit, but through which insects will not be apt to enter.

A further object is to provide an attachment of this character whichwill be simple and inexpensive in construction, efficient in operation,and which may be readily attached to various forms of window or doorscreens and be invisible from the exterior thereof.

With the above and other objects in view the invention consists ofcertain novel features of construction, combination, and ar rangement ofparts, as will be hereinafter described and claimed.

In the accompanying drawings, Figure 1 is an outer side view of theupper portion of a window-screen, showing the application of theinvention. Fig. 2 is a vertical sectional view of the same. Fig. 3 is ahorizontal sectional view through a portion of the upper bar of thescreen-frame and the escapement, and Fig. 4 is a detail perspective viewof the escapement removed from the screen.

Referring more particularly to the drawings, 1 denotes the escapement,which is preferably constructed of a single piece of sheet metal bent toform an outwardlycurved substantially triangular or upwardlytaperingbody portion 2, the upper or outer end of which is closed, as shown at3. In the outer curved side of the body portion 2, adj acent to theupper end thereof, is formed an exit-opening 4. The lower edge of thebulged or outwardly-extending portion is notched or cut away nearly upto the opening 4, as shown at 5, to permit of the entrance of light towhat would otherwise be a dark passage through which the flies wouldpass but slowly, if at all.

Formed integral with the inner edges of the lower portion of theescapement are laterally-projecting flanges 6, which are in a plane evenwith the inner edges of the body portion 2 and extend up substantiallyeven with the opening 4 and in which are formed openings 7 to receivetacks or other fastening devices, by means of which the escapement issecured to the screen-frame.

As will be noted by reference to Figs. 1 and 2, the escapement is of thesame length as the width of the screen-frame bar S, and by thusconstructing the article it is rendered invisible from the exterior ofthe screen or door, thereby obviating an objection common to suchattachments.

In arranging the device on a screen the same is inserted between theouter edge of the netting and the adjacent side of the screen-frame,with the inner or open side of the body portion of the escapementengaging the frame of the screen, said body portion 6 thus forming apassage through the open inner end of which flies or other insectscrawling on the inside of the screen may enter and pass out through theexit 4, which opens beyond the edges of the netting and outside the$010611, thus allowing the insects to pass out of the room. By providingthe opening 5 in the outer side of the body portion light is admitted tothe passage formed by the body portion of the escapement, so that theflies or other insects will not be deterred from entering and passingthrough the escapement.

By providing an esoapement such as herein shown and described andarranging the same on the screen a ready exit is provided through whichinsects may pass out, but will not readily enter.

The device may be attached to any form of screen adjacent to the outeredge of the same and is preferably, though not necessari ly, secured tothe upper cross-bar or frame of the screen, because of the well-knownpropensity of flies or other insects to crawl upwardly when seeking ameans of escape.

From the foregoing description, taken in connection with theaccompanying drawings, the construction and operation of the inventionwill be readily understood without requiring a more extendedexplanation.

Various changes in the form, proportion, and the minor details ofconstruction may be resorted to without departing from the principle orsacrificing any of the advantages of this invention as defined by theappended claims.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. As a new article of manufacture, an attachment for screen-doorscomprising an upwardly-tapering, bulged body portion having its upperend closed and the lower end open and the sides rovided withlaterally-extending perforate flanges, said flanges being in a planeeven with the inner edges of the body and the body being provided withan opening near its closed end and having its lower edges cut awaynearly up to said opening.

2. In combination with a screen-door, a fly-escapement secured to thetop bar thereof, said escapement comprising a bulged body portion havingits upper end closed and its lower end open, and the sides provided withperforated flanges which extend laterally in a plane even with the inneredges of the body and are secured to said frame, the body being providedwith an opening near its closed end and the lower edge being cut awaynearly up to said opening, and the screen material covering the cut-awayportion of said body, whereby the insect in passing through theattachment will be compelled to pass from the opening in the top of thebody down between t e body and the frame.

In testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses.

JOHN A. GEE.
